Using the same HTML fragment code on multiple pages_javascript tips

Problem Description
There is a relatively complex HTML fragment (A). If this HTML fragment is embedded into other pages (B, C, D...).
The key to the problem is that there is a lot of JavaScript logic that needs to be processed in the HTML fragment, such as paging, click event response, etc.

For this problem, we use a simple example to illustrate:
"There is a button on the page. Click this button to introduce an HTML fragment. There is a paging button in this HTML fragment."

1. Use IFrame
main page, click a button to introduce an IFrame to the page:

Copy code The code is as follows :

                                                                                                                            ="button" value="Next Page" class="next" />
                                                                                                                                                           >


2. AJAX returns page fragments and registers events
Note: We use textarea to simulate the returned HTML fragments.




Copy code


The code is as follows:

   
   
   

   

    <br>    <div id="complex_page_segment"> <br>        <input type="button" value="Previous Page" class="previous"><br>        <input type="button" value="Next Page" class="next"><br>        <div class="content">Page Content</div> <br>    </div> <br>   

由于我们需要在多个页面引用同一个HTML片段，这种方法导致大量事情处理被重复性的拷贝粘贴，明显我们需要将公共的方法提取出来。

3. AJAX返回页面片段，并调用页面片段中的函数注册事件

复制代码 代码如下:

   
   
   

   

    <br>    <script type="text/javascript"><BR>        function init_complex_page_segment() {<BR>            var parent = $("#complex_page_segment");<BR>            $(".previous", parent).click(function() {<BR>                $(".content", parent).html("Previous Page Content");<BR>            });<BR>            $(".next", parent).click(function() {<BR>                $(".content", parent).html("Next Page Content");<BR>            });<BR>        }<BR>    </script><br>    <div id="complex_page_segment"> <br>        <input type="button" value="Previous Page" class="previous"><br>        <input type="button" value="Next Page" class="next"><br>        <div class="content">Page Content</div> <br>    </div> <br>   

其实我们可以更进一步，完全没必要手工调用这个函数，而是可以在返回的HTML片段中让其自动执行。

4. AJAX返回页面片段，其事件自动注册

复制代码 代码如下:

   
   
   

   

    <br>    <script type="text/javascript"><BR>        $(function() {<BR>            var parent = $("#complex_page_segment");<BR>            $( ".previous", parent).click(function() {<BR>               $(".content", parent).html("이전 페이지 콘텐츠");<BR>            });<BR>            $(".next" ", parent).click(function() {<BR>                $(".content", parent).html("다음 페이지 콘텐츠");<BR>            });<BR>        });<BR>    < /script><BR>    <div id="complex_page_segment"><BR>        <input type="button" value="이전 페이지" class="previous" /><BR>        <input type=" 버튼" value="다음 페이지" class="next" /><BR>        <div class="content">페이지 콘텐츠</script>
